Calling *Save Game to slot* in Level which don't have Main Character

Hi, im trying to make inGame store but not in main level. So i need to call value of variable SaveCoins wich placed in saveSlot, and after purchase, i need to save game.
The main problem in that, ThirdPersonCharacter does not exist in this level, and if place it there its crushes everything. So the question is, how can i SaveGameToSlot if i cant call SaverSubClass which placed in ThirdPersonCharacter? Or there is no way to do so and i need to find another solution?
